May-12-20  spingo: Let's hope Ake Ullner saw the funny-bone side of this.

  perfidious: <nulltempus: 28. Kh2 …>

Even then, 28....Rxd3 is killtown.

May-12-20  stacase: A bit easier than yesterday. <nulltempus: 28. Kh2 ...> I wondered about that too, but as it turned out, White tipped his King over. One of those tips when you post says, "Nobody ever won by resigning" There should be another one that says, "Never question your opponent when he resigns"

  al wazir: <stacase: "Nobody ever won by resigning">. Yeah, as black I would have played on a few more moves.

  boringplayer: <perfidious> ..and h3 falls with check. There will be no joy in Mudville this day!
May-12-20  Brenin: 28 Red1 avoids the mate and protects the N, but then 28 ... Rxc4 is crushing.
May-12-20  AlicesKnight: <spingo: Let's hope Ake Ullner saw the funny-bone side of this.> - do you mean he found it humerus? Saw the gameline, including 28 Red1 Rxc4 possibility - "Black wins" but not quite clean-cut.
May-12-20  saturn2: I looked at
26...Nxf3+ 27. gxf3 Qxf3 28. Qh2 Rxd3 and black has 3 pawns more and h3 also will fall.

6...Le7 looks too passive and can be answered by 7.e4 So I would take 6....dxc4 or 6....Bb4

May-12-20  Brenin: After 28 Red1 Rxc4, White's best line seems to be 29 Qh2 Rxc1 30 Rxc1 Rxd3 31 Re1 (what else? It's almost zugzwang), but then White is helpless against 31 ... g4.
May-12-20  mel gibson: Easy one - White is left in a hopeless position.

May-12-20  zb2cr: Looks like Black gets extra material and a truly fine attack with 26. ... Nxf3+; 29. Kf1, Rxd3; 30. Qxd3, Nh2+; 31. Ke2, Qxg2+; 32. Ke3, Qxb2.

If White accepts the sacrifice, 27. gxf3, Qxf3 and now if 28. Kh2, Rxd3 White is in a mating net. If instead 28. Red1, Rxc4; 29. Qd2, Qh1+; 30. Ke1, Re4+; 31. Qe2, Qxe2#.

May-12-20  TheaN: Not incredibly easy imo, as there are some defensive options to consider. Obvious is <26....Nxf3+>, that aside.

Anything else but gxf3 at least follows Nxe1 -+. Black perhaps has better in some variations, but he'll be able to easily active Rc8 over the d-file and win without issue.

<27.gxf3 Qxf3>. First off, Black threatens R- and Qxd3. As White's position has turned into grated cheese he will have to defend against this. Knight moves fail: 28.Nf2 Qg2#; 28.Nf4 gxf4 -+ and 28.Nb4 Qh1+ 29.Kf2 Qg2+ 30.Ke3 Qf3# Black can build a staircase to the now opened d-file.

So a rook move: 28.Rcd1 Qh1+ 29.Kf2 Qh2+ 30.Ke3 Qxc2 -+. Oh yeah Rc1 was also doing that.

Most challenging is 28.Red1. Defends the knight, whom is still playing an active defensive role. Then it's a matter of activating the still passive pieces: either works. I went with the bishop: 28....Be4 -+ (-10) and White's hopeless against the pressure on d3. It is slightly worse than the c-Rook: 28....Rxc4! (-#11) which is the more logical piece to activate but I missed this shot. I'll take the 28....Be4 as a good alternative; finding either Rxc4! or Be4 is pretty tricky for a Tuesday, though.

May-12-20  TheaN: <saturn2: 6...Le7 looks too passive and can be answered by 7.e4 So I would take 6....dxc4 or 6....Bb4>

Whilst not typically semi-Slav theory Black's perfectly fine after 6....Be7. White committed his queen's knight early (5.Bd3 or even b3!? instead of Nc3=) and those positions tend to favor a draw due to the overall balance.

After 7.e4 dxe4 8.Nxe4 b6=; granted, Black will have to deal with the hole on d6 for most of the game, but he's solid either way.

May-12-20  sophiephilo: Got this.

But what if white responds with 28. Qh2?

May-12-20  TheaN: <sophiephilo: Got this.

But what if white responds with 28. Qh2?>

Many seem to consider Qh2 or Kh2, I never really did as after Rxd3 Black's up two pawns and the attack's still ongoing. That's just torture really.

  chrisowen: Recind must to go dock?
May-12-20  Brenin: <sophiephilo>: 28 Qh2 Rxd3, with the threat of 29 ... Rd2 30 Qxd2 Qh1+ 31 Kf2 Qg2+ 32 Ke3 Qf3+ 33 Kd4 Rd8 mate. White can prevent this, but only at the cost of further loss of material.

  Jimfromprovidence: After 26...Nxf3+ white also has also has 27 Kf2 as a response.

Black has two nice knight moves that work here, either 27...Nd4 or 27...Nh4.

I like the threat of 27...Nh4, seeing 28...Qxg2+, then 29 Ke3 Nf5#

  agb2002: White threatens Qxd2.

Black has Nxc4 and Nxf3+.

In the case of 26... Nxf3+ 27.gxf3 (else 27... Nxe1 wins an exchange and a pawn) 27... Qxf3:

A) 28.Red1 Be4 recovers the piece with a winning position.

B) 28.Nb4 Qh1+ 29.Kf2 Qg2+ 30.Ke3 Qf3#.

C) 28.Rcd1 Qh1+ 29.Kf2 Qg2+ 30.Ke3 Qxc2 wins decisive material.

D) 28.Kh2 Rxd3 wins.

E) 28.Nf2 Qg2#.
